The three-time All-Star point guard believes injuries and a different system are the reasons why.

“I’ve really had injuries while I’ve been with (the Nets) the whole time. And didn’t have the talent around me that I did (with the Jazz). And that system (in Utah) was a great system for my style of play. I’m a system player, and I loved Coach (Jerry) Sloan’s system. I loved the offense there.

” — Deron Williams

“I was injured the first year (and needed season-ending right wrist surgery),” Williams said Monday, a day before the Nets host the Jazz at Barclays Center. “I’ve really had injuries while I’ve been with (the Nets) the whole time. And didn’t have the talent around me that I did (with the Jazz).

“And that system (in Utah) was a great system for my style of play. I’m a system player, and I loved Coach (Jerry) Sloan’s system. I loved the offense there. We could’ve been a really good team. We just weren’t that good defensively as a group.”

Williams, 28, made the playoffs in four of his 5½ seasons with the Jazz. In 2010, NBA general managers voted him the best point guard in the NBA. But his play has tailed off ever since he was dealt.

In 90 mostly injury-plagued games with the Nets, Williams is averaging 19.2 points and 9.2 assists, but shooting just 39.6 percent, 32 percent from 3-point range.
